spoolmatic 30a

07-08-2013, 11:07 AM

running my spoolmatic off my bobcat for first time today. ran good off my shop 110 (for wc-115a) but when I try to run the 110 off the bobcat it don't want to weld? feeds ok. doesn't seem to have enough current to weld though. (yes I have my fine tune amps turned up on bobcat) Any ideas? do I just need to turn up my amps?

Do you have it set to CV constant voltage mode??

for MIG you will want CV mode NOT CC mode

and adjust your VOLTS not your amps...

Finally got back to it. I must have had something set wrong before. It ran great for a couple beads off the bobcat. Then the rpms dropped for a split second and everything went to crap. looked over and seen smoke(wc-115a). unplugged, shut it all down. pulled the cover off the wc-115a and the ground wire coming in is burnt. what ya think?

I don't know about the smoke....
but is the positive lead ran through the wc115? It has a current sensor that when current is detected, it switches from run in speed to set speed on the gun (wire feed speed).

Does your have a contactor?
Mine did not, so I bought one that had a 24v coil and installed it myself, the bobcat has to be in run for my contactor to close when I squeeze the trigger.

yes the pos lead runs through the wc115, through the contactor. the issue is with the 115v power for the drive rolls. it runs fine off shop power but not off the bobcat. It did run fine, but the wires got hot and fried the ground wire when run off the bobcat
